Chapter F, Problem A.37E

Interpretation Introduction

Interpretation:

Energy that have been recovered instead of getting dissipated as heat has to be calculated and also the energy that is used to drive the vehicle up the hill has to be found out.

Concept Introduction:

Kinetic energy is the energy that is possessed by a body when it is in motion.  Kinetic energy is represented as ${\text{E}}_k$.  The expression for kinetic energy is given as shown below;

    ${\text{E}}_k=\frac{1}{2}{\text{mν}}^2$

Where,

    $\text{m}$ is the mass of body.

    $\text{ν}$ is the velocity of body.
